Abstract (en)
The invention relates to a milling cutter tool suitable for gear hobbing, which comprises, on one hand, a basic body (1) having a geometrical centre axis (C1) around which the same is rotatable, and, on the other hand, a number of replaceable cutting bodies (2) each one of which includes a set of teeth (17), which are situated with a uniform partition (P) along a side of the cutting body. A support surface (9) for the individual cutting body formed in a pocket (8) of the basic body is tipped at a negative axial angle of at least 0,5° in relation to the centre axis of the basic body in order to locate the teeth (17) of the cutting body (2) along a common, imaginary helical line (X), which is concentric with the centre axis of the basic body and has an even pitch (P), which corresponds with the partition between the teeth.
